Developer Tools Downloads Figure 1. c. Select and hold (or right-click) Windows-driver-samples-master.zip, and choose Extract All. If you need more detailed instructions for setting up the target computer, see Preparing a Computer for Manual Driver Deployment. Provide the thread address you recorded earlier. Remember that WSL2 uses a real Linux kernel so there's no … The value for the key and port match what we set earlier using BCDEdit on the target. If you are debugging with GDB on Windows, see Windows Debugging with MinGW64. The computer where you install the driver is called the target computer or the test computer. The Brace character “}” will be highlighted as shown. This example output is for the cmd.exe process ID that was recorded earlier. Step through the code line-by-line by typing the p command or pressing F10 until you reach the following end of the AddDevice routine. For information, see x (Examine Symbols). You can find the location of a global variable address by typing ? To set a function breakpoint, on the Run view right-click inside the Breakpoints section, then choose Add Function Breakpoint and enter the name of the function on which you want to break execution. For example, look in the following folder: C:\Program Files (x86)\Windows Kits\10\Tools\x64\devcon.exe. To debug your Cygwin or MinGW application, add the miDebuggerPath property and set its value to the location of the corresponding gdb.exe for your Cygwin or MinGW environment. Note Record the first thread address associated with the two processes here. Conditional breakpoints enable you to break execution on a particular line of code only when the value of the condition is true. This is done by simple replacement pairs added in the sourceFileMap section. execute (when CPU fetches an instruction from the address), read/write (when CPU reads or writes to the address), write (when the CPU writes to the address). After you have set up the basics of your debugging environment as specified in the configuration tutorials for each target compiler/platform, you can learn more details about debugging C/C++ in this section. Now, use the !process command to try to look at the process ID that had been associated with echoapp.exe that you recorded earlier. In Solution Explorer, you can see one solution that has three projects. Enter g into the debugger to restart code execution on the target system. Each processor has an IRQL setting that threads can raise or lower. The commands to view and set threads are very similar to those of processes. Here's the general syntax for the devcon tool that you will use to install the driver: The INF file required for installing this driver is echo.inf. It will hit the breakpoint in the read and write event a number of times. Source debugging and access to local variables are more difficult, and sometimes nearly impossible, if the code has been optimized. WSL 2 includes a Linux kernel, so this is very similar to executing the app on an actual … As expected, the current thread is the thread associated with echoapp.exe and it is in a running state. You type commands in the smaller pane (the command entry pane) at the bottom of the window and view the command output in the larger pane at the top of the window. To learn more, see Configuring C/C++ debugging. The call stack is the chain of function calls that have led to the current location of the program counter. For information about how to use the Ethernet transport protocol, see Getting Started with WinDbg (Kernel-Mode). This diagram shows a more complex device node tree. Alternatively, you can also modify breakpoints by selecting edit > breakpoints in WinDbg. If you have any other questions or run into any issues, please file an issue on GitHub. This example output is for the echoapp.exe process ID that was recorded earlier. What we do use heavily is C# Interactive in Visual Studio. Note Specify a new folder, or browse to an existing one that will store the extracted files. For debugging, it is best if the linker does not optimize your code. The actual source files themselves must also be accessible to the debugger. Use the !devnode 0 1 echo command to display Plug and Play information associated with our echo device driver as shown below. Understand source code symbol requirements. (If the programming language is C or C++ and WinDbg is in source mode, source mode can be turned on or off using Debug>Source Mode). Bash script for Ubuntu (and derivatives as LinuxMint) to easily (un)install kernels from the Ubuntu Kernel PPA.. Warnings ⚠️ Use this script at your own risk. Windows debugger runs on the host system and the KMDF Echo driver runs on the target system. a. You can read the Custom views for native objects topic for details on using Natvis with the C/C++ extension. You can also set breakpoints that fire when a memory location is accessed. Note The .reload command with the /f force option deletes all symbol information for the specified module and reloads the symbols. You hit F5, VisualGDB does the rest. List the breakpoints to confirm that the breakpoint is set properly. In Microsoft Visual Studio, select File > Open > Project/Solution... and navigate to the folder that contains the extracted files (for example, C:\DriverSamples\general\echo\kmdf). This technique can be very valuable for debugging complex kernel mode code issues. This command will use bu or bp appropriately and allows wildcards * to be used to set breakpoints on every symbols that matches (like all methods in a class). Download and extract the KMDF Echo sample from GitHub. Enter this command to enable debugging. Use the view> local menu item to display local variables. View information about the driver by performing the following steps. If a call is encountered, code execution passes over the call without entering the called routine. An information (INF) file that contains information needed to install the driver. You can also use CTRL+C, to copy the address to the copy buffer for later use. Note Run to cursor (F7 or Ctrl+F10) – Place the cursor in a source or disassembly window where you want the execution to break, then press F7; code execution will run to that point. You can then step forward in the code from that point, to debug that specific section of code. Set the mask to 0x00000000 if you would like to reduce the amount of information that is displayed. Provide your echoapp.exe process address that you recorded earlier, instead of the example process address shown below. To download and build the Echo sample audio driver, perform the following steps. The top function on the call stack is the current function, and the next function is the function that called the current function, and so on. To install the driver on the target system, perform the following steps. If you get an error message about devcon not being recognized, try adding the path to the devcon tool. It is possible to experience several internal errors during a build attempt for the Debug configuration under Visual Studio where it is common to have /debug-parameter and /debug options enabled simultaneously. The following are the commands that you can use to step through your code (with the associated keyboard short cuts shown in parentheses). If you make any configuration and/or platform changes for one project, you must make the same changes for the remaining three projects. The interrupt request level (IRQL) is used to manage the priority of interrupt servicing. Set the sample's configuration and platform. This is useful if you've seen enough of the routine. Note Output that has been omitted is indicated with "… " in this lab. Use Ctrl+F to search in the output that is generated to look for the name of the device driver, echo. Stepping through code from the Debugger Command window. Run (F5) – Run until a breakpoint is encountered or an event like a bug check occurs. Enter the !devstack command to display Plug and Play information associated with the device driver. When attached to a process with GDB, break-all will end the process. Navigate to the folder that contains the built files for the Autosync driver: C:\DriverSamples\general\echo\kmdf\driver\AutoSync\x64\Debug. In Section 6, you will display information about the echo sample device driver and where it lives in the Plug and Play device tree. The output above shows that DeviceAdd method for our echo driver is ECHO!EchoEvtDeviceAdd. In the output, use CTRL+F to locate the same process address for the process associated with the echoapp.exe image. Breakpoints are used to stop code execution at a particular line of code. By default it is located here. Use the IP address of the host system that you recorded earlier, not the one shown. In Section 1, you will configure network debugging on the host and target system. That means dev/test/run native Linux on Windows right from VS. We will set a breakpoint to examine the process that are used when a sound is played. The new Visual Studio extension allows us to quickly run and debug a .NET application on WSL 2 from Visual Studio. Clear the previous breakpoints using bc *. Before you deploy a test signed driver, you must prepare the target computer by enabling test signing. For more information, see Source Code Debugging in WinDbg in the debugging reference documentation. The process of moving the driver package to the target computer and installing the driver is called deploying the driver. Additional information is available on Windows debugging. For more information about setting up the target computer, see Preparing a Computer for Manual Driver Deployment and Setting Up KDNET Network Kernel Debugging Automatically. It can gain access to any part of any other process running in either user mode or kernel mode. To request detailed information about a specific module, use the v (verbose) option as shown. When debugging is stopped the Terminal window is not closed. In this lab, a live kernel debug connection is used to … The breakpoint will be hit and code execution will halt. Use the !process command to confirm that you are now running a different process. Use the !process command to list process information for both processes running your PC. In Section 9, you will display information about the process and threads running in kernel mode. This is due to, Core dumps cannot be loaded when debugging with GDB because GDB. These two asks are far higher-impact for the vast majority of your customers than anything you could do … These symbol files will show the debugger how the binary instructions correspond to the source lines. "/path/to/symbols;/another/path/to/symbols", "/build/gcc-4.8-fNUjSI/gcc-4.8-4.8.4/build/i686-linux-gnu/libstdc++-v3/include/i686-linux-gnu", "/build/gcc-4.8-fNUjSI/gcc-4.8-4.8.4/build/i686-linux-gnu/libstdc++-v3/include", Configure IntelliSense for cross-compiling, does not support the core dump format used in macOS, Configure VS Code for Windows Subsystem for Linux, GDB, LLDB, and LLDB-MI Commands (GDB/LLDB). For example, if you left the default settings unchanged, then the compiled driver files will be saved to a folder named \x64\Debug for a 64 bit, debug build. To view the threads that are running, type !thread. In Section 3, you will download and build the KMDF echo driver. In addition, this sample is used to illustrate how you can single step through native kernel mode code. You can use a browser to view the echo sample in GitHub here: https://github.com/Microsoft/Windows-driver-samples/tree/master/general/echo/kmdf, https://github.com/microsoft/Windows-driver-samples/blob/master/general/echo/kmdf/README.md. Note that some of these books will use older versions of Windows such as Windows Vista in their examples, but the concepts discussed are applicable to most versions of Windows. In the output shown below, the process with the Image value of System is different from the Echo Image value. Select and hold (or right-click) the KMDF Echo driver entry again and select Enable from the menu. Use Ctrl+Break (Scroll Lock) to break into the code running on the target system. In the editor, conditional breakpoints are indicated by a breakpoint symbol that has a black equals sign inside of it. To view the output show here, repeat the steps described previously, if necessary. In the next section, we will examine the state of the variables after the DeviceAdd code has executed. Be aware that the kernels installed by this script are unsupported 🔓 Do not use this script if you don't have to or don't know … Use standard commands (Call stacks, variables, threads, IRQL), Use advanced driver debugging commands (!commands), A laptop or desktop computer (host) running Windows 10, A laptop or desktop computer (target) running Windows 10, A network hub/router and network cables to connect the two PCs, Access to the internet to download symbol files, Windows Software Development Kit (SDK) for Windows 10, Open a command prompt on the host system and type, Record the IP address of the host system: ______________________________________, Open a command prompt on the target system and use the. (If this is not already open, choose Solution Explorer from the View menu.) This opens a small peek window where you can enter the condition that must evaluate to true in order for the breakpoint to be hit during debugging. The compiler will create symbol files (.pdb files). For information about contents of the register, see x86 Architecture and x64 Architecture. In a minute or two, debug output should be displayed on the host system. You can display the names and values of all local variables for a given frame by typing the dv command. To add your local symbol location to use your local symbols, add the path using .sympath+ and then .reload /f. The echo device driver should be loaded. The PnPManager is a root node. Function breakpoints enable you to break execution at the beginning of a function instead of on a particular line of code. Note See, When attaching to a process with GDB, the application being debugged cannot be interrupted. Step 1: Install Visual Studio 2019; Step 2: Install WDK for Windows 10, version 2004; Step 3: Clone the Driver Module Framework (DMF) into the same parent directory. Typically, you would be working with your own driver code when you use WinDbg. Step in (F11) – This command is like step-over, except that the execution of a call does go into the called routine. Note You must load the proper symbols to use advanced functionality that WinDbg provides. To set the symbols path to the Microsoft symbol server in the WinDbg environment, use the .symfix command. Use the dd command to display confirm the mask is set to display all of the debugger messages. If you are having problems viewing local variables or source lines, set the following build options: Type the following in the command area of the debugger to display information about the echo driver : Because we set prefer_dml =1 earlier, some elements of the output are hot links that you can select. Type the following to change the default debug bit mask so that all debug messages from the target system will be displayed in the debugger. You can access reference command help using the .hh command. On the target computer, select and hold (or right-click) the certificate file, and select Install, then follow the prompts to install the test certificate. In Visual Studio, select Build > Build Solution. Be sure and use the g command to let the target computer run code, so that it can be used. On the target computer, in a Command Prompt window, enter devmgmt open Device Manager. Cmd.exe: ____________________________________________________________, EchoApp.exe: _______________________________________________________. Copy devcon.exe to the target system. Also on the driver’s properties make sure Driver Signing > Sign Mode is set to “Test Sign”. The call stack shows that the kernel (nt) called into Plug and Play code (PnP), that called driver framework code (WDF) that subsequently called the echo driver DeviceAdd function. Information about the device driver in the Plug and Play device tree can be useful for troubleshooting. Alternatively, we could review the source code to locate the desired function name for our breakpoint. It also a good idea to clear any break points using bc *, so that the target computer won't break and try to connect to the host computer debugger. A dialog box will appear indicating that the test driver is an unsigned driver. This lab assumes that you are stopped at the AddDevice routine using the process described earlier. The output shows that the process is associated with the echoapp.exe which was running when our breakpoint on the driver write event was hit. Disables a breakpoint. For more information see r (Registers). The source file location can be changed if the source files are not located in the compilation location. GDB will only bind breakpoints set while the application is not running (either before attaching to the application, or while the application is in a stopped state). Break in (Ctrl+Break) - This command will interrupt a system as long as the system is running and is in communication with WinDbg (the sequence in the Kernel Debugger is Ctrl+C). Use Ctrl+Break (Scroll Lock) in WinDBg to break into the code running on the target system. In Section 2, you will use debug commands to display information about the target system. Without this setting, you have to install the MSVC runtime to the target computer separately. The output displayed in the !devnode 0 1 command includes the PDO address associated with the running instance of our driver, in this example it is 0xffffe0007b71a960. Sets a breakpoint for a symbol. The debug command output will display "Breakpoint 1 hit". Your output should be similar to the text shown below. WinDbg is used to debug the echo kernel mode sample driver code. The symbol files do not contain the text of the source code. If you need additional debug support in order to diagnose an issue in your code cells, you can export it as a Python file. Debug a Jupyter Notebook. This lab includes exercises that introduce the debugging tools, teach common debugging commands, illustrate the use of break points, and show the use of the debugging extensions. Version 1.55 is now available! Select the Browse all global symbols link in the debug output to display information about items symbols that start with the letter “a”. If there are additional directories where the debugger can find symbol files (for example, .pdb files for the Visual Studio Windows Debugger), they can be specified by adding the additionalSOLibSearchPath (for GDB or LLDB) or symbolSearchPath (for the Visual Studio Windows Debugger). To disable this error temporarily, use the following command: echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope. Type this command to confirm that the dbgsettings they are set properly. b. Download the master.zip file to your local hard drive. In Windows 10, select Troubleshoot > Advanced options > Startup Settings , then select Restart button. In Update and Security, select Recovery. The open-source VSCode is a code editor redefined and optimized for building and … In the device tree, locate Sample WDF Echo Driver in the Sample Device node. Use a network hub/router and network cables to connect the two PCs. Navigate to the Tools folder in your WDK installation and locate the DevCon tool. Build the DmfK project with Release and Debug configurations for all architectures (x64 and Win32). To set a breakpoint when the application is running (not stopped under the debugger), or to pause the application being debugged, press, When debugging with LLDB, if the Terminal window is closed while in break mode, debugging does not stop. To enable kernel mode debugging on the target system, perform the following steps. Note In addition, the echoapp.exe file was built and it should be located here: C:\DriverSamples\general\echo\kmdf\exe\x64\Debug. We need it ported to .NET Core. The KMDF Echo sample is located in the general folder. Add your local symbol location to the symbol path by typing the following command. For more information about assembly language disassembly, see Annotated x86 Disassembly and Annotated x64 Disassembly. The Debugger Command window is the primary debugging information window in WinDbg. We need it integrated with active debug sessions. Set the breakpoint with the bm command using the name of the driver, followed by the function name (for example AddDevice) where you want to set the breakpoint, separated by an exclamation mark. Double-click the kmdfecho solution file to open it. Note You can alternatively use !process 0 17 to display detailed information about every process. Sets a breakpoint that will be active until the module it is in is unloaded. Use the !Thread command to display information about the current thread. Enables a breakpoint. For example, to set a read/write breakpoint on a specific memory address, you could use a command like this. Interrupts that occur above the processor's IRQL setting take precedence over the current operation. Re-enable these security features when testing is complete and appropriately manage the test PC, when the security features are disabled. WinDbg is used to debug the echo kernel mode sample driver code. Note For more information about more complex driver stacks, see Driver stacks and Device nodes and device stacks. The PCs in this lab need to be configured to use an Ethernet network connection for kernel debugging. As it turns out, the echo sample doesn’t contain any symbols that start with the letter “a”, so type x ECHO!Echo* to display information about all of the symbols associated with echo driver that start with Echo. In the next section, you will copy the code to the target system, and install and test the driver. To set a breakpoint using a debug command, use one of the following b commands. When echoapp.exe finishes, break in to the debugger, by pressing CTRL+ScrLk (Ctrl+Break). If that is not the case, the best approach is to run the same "bitness" of tools on the host that the target is running. You can build directly within Visual Studio. See Enable logging for the debug adapter to learn how to get C/C++ extension logs. Note that the breakpoint dialog box only works with existing breakpoints. User mode - Applications and subsystems run on the computer in user mode. We will use AddDevice to watch the driver being loaded. To become familiar with WinDbg operation, the KMDF Template "Echo" sample driver is used. Before using BCDEdit to change boot information you may need to temporarily suspend Windows security features such as BitLocker and Secure Boot on the test PC. The exercise also covers debug extensions (sometimes called "!commands") that are used for kernel-mode debugging. %windir%\inf\setupapi.dev.log. Display the contents of the registers for the current thread on the current processor by using the r (Registers) command. Locate a USB thumb drive or set up a network share to copy the built driver files and the test EchoApp from the host to the target system. On the target computer, open a Command Prompt window as Administrator. You will need the following software to be able to complete the lab. The new release includes support for .NET 6 Preview 1 and testing Unity applications. Visual Studio 2008 Express works too, but doesn’t provide a 64-bit compiler. Lab objectives. When the test app runs, the I/O routine in the driver will be called. In Section 4, you will use devcon to install the echo sample driver. In Device Manager, on the View menu, choose Devices by type. If all goes well, the build windows should display a message indicating that the build for all three projects succeeded. To be able to step through code and check the values of variables in real time, we need to enable breakpoints and set a path to the source code. Displays the stacks and the full list of parameters. This labs assumes that both PCs are running a 64 bit version of Windows on both the target and host. Select Install this driver anyway to proceed. ubuntu-mainline-kernel.sh. Much of the core OS functionality and many hardware device drivers run in kernel mode. The lab has the following eleven sections. Open the driver solution in Visual Studio. If you want to keep the call stack available, you can select. Enable the ability to run test signed drivers: b. This exercise covers debug commands that are frequently used during both user-mode and kernel-mode debugging. In the command entry pane, use the up arrow and down arrow keys to scroll through the command history. You can modify existing breakpoints by using the following commands: Clears a breakpoint from the list. The output from this command can be lengthy. For additional information, see Symbol Stores and Symbol Servers. Type echoapp to start the test echo app to confirm that the driver is functional. Displays the stack and first three parameters. To end a user-mode debugging session, return the debugger to dormant mode, and set the target application to run again, enter the qd (Quit and Detach) command.
